How does gravity light work?

GravityLight is powered through weight. As the weight falls it turns a gear drive train, driving the DC generator that powers the LEDs. There is no battery, no sunlight, no solar and costs nothing to run. It takes 2-3 seconds on manual weight lifting the weight that powers gravity light, creating 30-35 minutes of light on its descent.

How do solar lights work?

Solar lights use photovoltaic (PV) cells, which absorb the sun’s energy and create an electrical charge that moves through the panel. Wires from the solar cell connect to the battery, which converts and stores the power as chemical energy until it's needed. The battery later uses that energy to power an LED (light-emitting diode) bulb.

What is solar power & how does it work?

In the first quarter of 21st century, solar power was the third most widely utilized form of renewable energy after hydroelectric power and wind power; in 2022 it accounted for about 4.5 percent of the world’s total power generation capacity. The majority of the world’s solar power comes from solar photovoltaics (solar panels).
